What's the best way to make art available for open source projects

Aside from coding I’m interested in making art for games and other projects. In the absence of a specific request I try to publish about two assets daily, 5 days a week. To make these as appealing and useful as possible I am wondering a couple of things.

When it comes to art assets for open source games and other projects what sizes and formats are most useful for you? Is it best to just have the highest res pic possible so you can scale down from there? Or is it important to have a variety of formats, etc? Also what things do you look for the most when looking for images for games and other applications?


@crysjreid if you haven’t already checked it out, http://opengameart.org/ has a ton of assets, and you may be able to expand upon them or at least adopt their conventions.

We could definitely use help from good graphic artists and designers, and have a ton of open issues if you want to take a look.
